There's only a VidonXBMC-13.2_V1.0.0.0.apk that I'm aware of. It's available on VidOn's forum here.

Finally tested VC-1 for myself. I'm now on SDK 1.3 and VidOn XBMC v1.0.0.0...
- VC-1 23.976 1080p, plays fine (something HiMedia Q5 can't). Except for microstutters as with all 23.976
- VC-1 29.970 1080i playback is a pixellated mess

Also re-tested MPEG2:
- 1080i either has lip sync issues or video is jumpy (almost strobe-like effect)
- 720p plays fine

Finally, 3D ISO playback, with SDK 1.3 and VidOn XBMC v1.0.0.0 is NOT as good as SDK 1.2 and VidOn XBMC v0.0.0.4 or later (including v1.0.0.0). So, basically stick with SDK 1.2 and get 720p UI XBMC, or switch to SDK 1.3 for 1080p UI, but worse video playback. More buffering between chapter skips, picture not smooth (more frame skips), etc. With 'Avatar' 3D, playback had strobe-like movement and stuttered with audio out of sync.

I am at the end of the road with VidOn. Will be putting my 2x units on eBay. It served me fine for about 5 months, but now I prefer to use HiMedia's Q5 4K. It ain't perfect either, but overall playback is better, as is PQ, and box is snappier. Until something better comes along, it'll do just fine.
